Abstract: A dynamic seal (36) is provided between a rotatable ball control member (24) and a noise attenuator (40) in a fluid control valve (10). In one embodiment a noise attenuator is rigidly clamped in the valve body (12) and a floating, spring biased seal is provided in the attenuator and facing the ball. A bi- directional fluid control valve is provided with two rigidly mounted noise attenuators each having a floating, spring biased ball seal. In a second embodiment a noise attenuator is floating, spring biased towards the ball and includes an annular seal retained in the attenuator. Pressure balancing the fluid flow pressure and the spring bias enables substantially zero seal engagement with the ball during ball rotation, while enabling a reliable seal of the ball in the shut-off valve position.

Abstract: A circumscribing apparatus for marking a circular reference line about a cylindrical object has a first side. A first frame member has two spaced-apart guide members extending outwardly on the first side of the apparatus. The two guide members fall along a first straight line. A second frame member extends outwardly from the first frame member to a position on a second straight line which is perpendicular to the first line. A scribe is connected to the second member adjacent the position and has a marker extending outwardly on the first side of the apparatus. The apparatus can be used in conjunction with a wrap-around sleeve placed about the cylindrical object. The sleeve has a straight edge which extends about the object along a circular path when the sleeve is fitted. The apparatus is placed against the object with the two spaced-apart guide members contacting the edge. The marker is held against the object at a position spaced-apart outwardly from the edge. The apparatus is moved about the object so the projections stay in contact with the edge and the marker marks a circular line about the object.

Title: Telecommunications switch having a universal applications program interface for standardized interactive call processing communications
Inventor: HEBERT MARK P
IPC: H04Q3/545
Filed: 1996-11-27
Granted: 2006-06-06
Abstract: The present invention is a standardized host-to-switch application program interface (API) for performing call control processing, capable of being customized to meet telecommunications application and network signalling protocol requirements. The universal API comprises one or more generic messages having programmable fields for transmitting commands, status, and data between the host application and the switch.      The present invention further comprises a programmable telecommunication switch that provides a user with the ability to define a desired API protocol, either "standard" or custom in nature, for performing any desired , switching functions.      The present invention includes a protocol development environment which enables a user to define a separate finite state machine for each port provided by the switch. Each finite state machine may be independently defined by combining a series of elementary processing steps, called atomic functions, into primitives, which are in turn combined with states and events to define the desired state machine. Such state machines may include atomic functions configured to generate predetermined messages under predetermined conditions and containing predetermined information. Such state machines may further include the ability to respond to state events that include the receipt of generic API messages configured to provide the state machine with information from the host application.

Granted: 2000-07-18
Abstract: A graphical application developing and managing environment is described capable of representing and editing program modules using multiple display formats, which include embedding source code written in a functional language into a spreadsheet-like format. Methods are described for enabling the sharing of program modules by defining standardized interfaces into program modules and existing documents and by centrally locating module definitions. A patchwork mechanism is described requiring only basic spreadsheet editing skills on behalf of the user, enabling a user of the environment to connect external documents and program modules into a new program application. The invention allows complicated programming and simple end-user programming to be achieved within a unified environment and allows the execution of program modules and tracing of variables simultaneously with the writing of a program application. The invention defines methods for representing the various parts of a source code, defining a program application, along with the application icon as determined by a user creating the application and thereby making parts of the source code accessible to end-users for run-time execution.

Abstract: A fiber-optic device (10) for sensing the presence of a gas in an environment is provided. The device (10) comprises a light source (14) for directing a light beam (36) to a layer system having a first surface (46) and a second surface (54) opposite to the first surface.  The first surface (46) is exposable to the light beam (36) and the second surface is exposable to the environment. A first light portion (50) encounters and reflects from the first surface (46) at an angle of incidence free from optical wave guide resonance phenomenon and the second light portion (52) encounters and reflects from the first surface (46) at an angle of incidence enabling an optical wave guide resonance phenomenon. The layer system is selected to reversibly react with the gas to be detected. The reaction between the gas and the material changes the material's optical properties and the wavelength at which the optical wave guide resonance occurs. Furthermore, a mechanism (24, 26, 28) for measuring the intensity of the reflected first light portion (50) relative to the reflected second light portion (52) is provided with the ratio of the first and second light portions indicating the concentration of the gas presence in the environment.

Abstract: A can with a cover comprises a pull ring (5) and a score line (7) adjacent the closing flange (8) of the cover, and a bottom closing flange (9). The nose (5b) of the pull ring (5) is spaced such a distance (x) from the weakening line (7) that two cans (1', 1 ) can be stacked atop one another without any risks of damaging the pull ring. When the handle part (5a) is lifted, the pull ring is displaced the distance (x) outwards towards the cover flange (8) before it perforates the cover through the score line (7). The resulting can is less vulnerable compared to known cans at the score line during handling and can thus withstand heavy vertical loads. Moreover more room is provided for a closing chuck at the seaming of the cover.

Abstract: An optical reading head system has a calibrated pixel output, consisting of a discrete value for each of a plurality of pixels. The system has a scanning station (10) with an exposure region that includes an image region and a detector (35) including an array of photosensitive sites (30a) that sense reflected light from the exposure region during a detector exposure period to generate a pixel output profile of the image region. There are a plurality of light sources (20a, 21a) for lighting the exposure region. Each light source emits an individually controllable amount of light to the exposure region during a detector exposure period such that the system's pixel output is acceptably calibrated. A calibration medium is supplied with a calibration region, and a target pixel output profile is defined for the calibration. The individually controllable light sources are adjusted to make the pixel output file acceptably within range of the target pixel output profile.
